The University of Maryland participated in three TREC-6 tasks: ad hoc retrieval, cross-language retrieval, and spoken document retrieval. The principal focus of the work was evaluation of a crosslanguage text retrieval technique based on fully automatic machine translation. The results show that approaches based on document translation can be approximately as e ective as approaches based on query translation, but that additional work will be needed to develop a solid basis for choosing between the two in speci c applications. Ad hoc and spoken document retrieval results are also presented.
